Step-by-step explanation: we know this because the total about of questions on the test is 20 and for the score to add up to 100% each question has to be worth 5% so we can just do 5 x 18 to get 90%. or (5 x 2) - 100 to also get 90%

What is the length of the missing leg? If necessary, round to the nearest tenth.

KengaRu [80]

Answer:

a = 3.5

Step-by-step explanation:

Let's find 'a' using Pythagoras theorem.

=> 4² = 2² + a²
=> 16 = 4 + a²
=> 12 = a²
=> a = √12
=> a = √2 x 2 x 3
=> a = 2√3
=> a = 2 x √3
=> a = 2 x 1.732
=> a = 3.464 = 3.5 (Estimated)

7g + 11 subtracted from 12

BlackZzzverrR [31]

A subtracted from b means b-a

7g+11 subtracted from 12 means 12-(7g+11)=12-1(7g+11)=12-7g-11=12-11-7g=1-7g
